Also, they want the game to be popular as soon as possible so there are no
security requirements to sign up or set up a user account(userid/pwd). They
just want user to download and start playing.

Maybe upon download and installation, you automatically register the user
(with a username/password or a uid or something...) and automatically
install it on his client.
The user must save this 'code/password/whatever' if he wants to re-install
or transfer his client to another device and still have his online property
there for him.

Hi
I recently joined a company which is developing a game/app for iOS. Game
needs some intensive server side processing. Also, they want the game to be
popular as soon as possible so there are no security requirements to sign up
or set up a user account(userid/pwd). They just want user to download and
start playing.
How do you secure server resources(say REST services) in this environment?
Every approach i think of, has a security flaw, because fundamentally
anything you store on client side(hardcode in code or config files,
encryption keys etc) to communicate with server side resources, it can be
retrieved.
May be I am missing something fundamental. Any help is appreciated.
Thanks
